Okii Systems FC1 USB Focus Controller

The Okii FC1 USB Focus Controller connects to a Canon DSLR by USB cable and controls focusing and common camera functions. The unit is compatible with the 1D C, 1D X, 1D Mk IV, 5D Mk III/II, 7D, 6D, 70D, 60D, T5i, T4i, T3i, T2i, and T1i, and with all Canon, Sigma, and Tamron autofocus lenses. Tokina lenses are also compatible, but can experience camera lock ups with the Canon 7D if the focus command rate is set faster than the lens is able to move the internal focus element. Manual focus lenses will not have focus control, but other functions, such as settings changes or video start/stop, will work.
